Selective oxidation of benzyl alcohol to benzaldehyde over CoFe2O4 nanocatalyst

Co/Fe bimetallic spherical nanomaterials were synthesized by hydrothermal method as an efficient heteroge-neous catalyst, which can catalyze the selective oxidation of benzyl alcohol to benzaldehyde by O2, thereby replacing stoichiometric oxidation reagents such as chromate and manganese oxide. CoFe2O4 has good oxidation activity and selectivity for benzyl alcohol. The catalyst catalyzes the preparation of formaldehyde from benzyl alcohol oxide by O2 at 150 degrees C, with a conversion rate of 95.3% and a yield of 96.7%. Furthermore, the catalyst is recycled for 5 consecutive uses without significant degradation of its catalytic performance.

Automated summary

Co/Fe bimetallic spherical nanomaterials synthesized by hydrothermal method exhibit excellent catalytic performance for the selective oxidation of benzyl alcohol to benzaldehyde, providing an alternative to less environmentally friendly oxidation reagents. The catalyst achieves high conversion and yield under suitable conditions and maintains stable catalytic performance after multiple cycles of use.
